Laravel Carve

Carve markup language integration for Laravel — Blade directives, services, validation, and caching.

Installation

composer require markup-carve/laravel-carve

The service provider and Carve facade alias are auto-discovered via Laravel's package discovery.

Optionally publish the config:

php artisan vendor:publish --tag=carve-config

Usage

Blade Directives

{{-- Safe by default - XSS protection enabled --}}
@carve($article->body)

{{-- For trusted content only - no XSS protection --}}
@carveRaw($trustedContent)

{{-- Plain text output (escaped) --}}
@carveText($article->body)

Facade

use MarkupCarve\LaravelCarve\Facades\Carve;

$html = Carve::toHtml($source);
$text = Carve::toText($source);
$raw  = Carve::toHtmlRaw($trustedSource);

Dependency Injection

use MarkupCarve\LaravelCarve\Service\CarveConverterInterface;
use MarkupCarve\LaravelCarve\Service\CarveManager;

class ArticleController
{
    public function __construct(
        private CarveConverterInterface $carve,
        private CarveManager $manager,
    ) {}

    public function show(Article $article): View
    {
        return view('article.show', [
            'html' => $this->carve->toHtml($article->body),
            'text' => $this->carve->toText($article->body),
            'docs' => $this->manager->toHtml($article->body, 'docs'),
        ]);
    }
}

Configuration

// config/carve.php
return [
    'converters' => [
        // Default has safe_mode: true (XSS protection enabled)
        'default' => [
            'safe_mode' => true,
        ],

        // For trusted content (admin, CMS)
        'trusted' => [
            'safe_mode' => false,
        ],
    ],
    'cache' => [
        'enabled' => false,
        'store' => null,
    ],
];

Multiple Converter Profiles

Use different configurations for different contexts:

{{-- Default is safe --}}
@carve($comment->body)

{{-- Use named converter for trusted content --}}
{!! Carve::toHtml($article->body, 'trusted') !!}

{{-- Or use @carveRaw for quick trusted rendering --}}
@carveRaw($article->body)

Safe Mode

Safe mode is enabled by default for XSS protection. Disable only for trusted content:

'converters' => [
    'trusted' => [
        'safe_mode' => false,
    ],
],

Extensions

Enable carve-php extensions per converter:

'converters' => [
    'default' => [
        'extensions' => [
            ['type' => 'autolink'],
            ['type' => 'smart_quotes'],
            [
                'type' => 'heading_permalinks',
                'symbol' => '#',
                'position' => 'after',
            ],
        ],
    ],
    'with_mentions' => [
        'extensions' => [
            [
                'type' => 'mentions',
                'user_url_template' => 'https://github.com/{username}',
            ],
            'table_of_contents',
        ],
    ],

What is Carve?

Carve is a post-Markdown lightweight markup language. It builds on the foundations of Djot, John MacFarlane's post-Markdown project, and offers cleaner syntax and more features than Markdown while being easier to parse.

Learn more about Carve syntax at github.com/markup-carve/carve.

Ecosystem

This package is part of the Carve organization - the spec with its conformance corpus, three byte-identical reference implementations (JS, PHP, Rust), editor plugins, and framework integrations. See awesome-carve for a curated list of everything Carve.
